bHomingStartStop
BOOL
: Start/stop homing
• Only possible in the "referencing" operating mode.
TRUE If one of homing modes "4" ... "15" in
is selected:
Start reference search
• The current status of the reference search is indicated via the
status outputs bHomingDone and bHomePosAvailable.
If homing mode "100: SetRef" is selected in
:
Setting the home position manually
• The home position is set manually with the drive at a standstill.
The current actual position now corresponds to the reference
position set in
in the machine measuring system.
TRUEFALSE Stop homing.
• If the bHomingStartStop input is reset to FALSE during active
referencing, homing is cancelled and the drive is brought to a
standstill.
bHomingSetPos
BOOL
: Set home position ("on the fly" homing)
• With referencing "on the fly", the home position of a machine can be set during
ongoing movement. Jerking and compensating movements do not occur.
FALSETRUE The position at the dnMotorRefOffset_p input of
the
SB at the instant of activation is the set
home position.
bHomingResetPos
BOOL
: Delete home position
Note: With this function, positions are not deleted but only the status signals
bHomePosAvailable and bHomePosDone are reset. Setpoints and actual positions
remain untouched until a renewed reference setting or homing.
FALSETRUE The internal status "reference known" is reset.
• The controller is no longer referenced.
• The process outputs bHomePosAvailable and bHomingDone are
reset to FALSE.
bEnableVelOverride
BOOL
TRUE Activate speed override
bEnableAccOverride
BOOL
TRUE Activate acceleration override
bEnableSRampOverride
BOOL
Note!
If the nSRampOverride_a input on the LS MotionControlKernel remains
unconnected or if "0 %" is specified as the override value, activation of the S-ramp
override results in deactivation of the S-ramp time.
• Deactivation of the S-ramp time before the start of a profile with S-ramp time
causes linear ramp generation.
• Deactivation of the S-ramp time during a traversing process, however, is not
accepted immediately in the profile generator, but the profile generator checks
automatically when an online change of the ramp form can be carried out and
then initiates it automatically.
TRUE Activate S-ramp smoothing override
bPosExecute
BOOL
: Start travelling
FALSETRUE Execute selected profile
bPosExecuteFinish
BOOL
: Complete cancelled profile
FALSETRUE A positioning process previously cancelled, e.g. by bPosStop or due to
a device error, is resumed by travelling to the original target.
bPosDisableFollowProfile
BOOL
: Do not execute sequence profile (switch-off profile linkage)
TRUE Evaluation of the sequence profile number parameterised in
for the selected profile is suppressed.
